If the notebook does not come with a M.2 NVMe SSD: Stay away: It's old stock on the way out. NVMe SSDs are many - many times faster than old HDDs or even old SATA SSDs. They plug directly into the PCIe bus, so they are not limited by the slow speed of old serial SATA buses. PCIe buses transmit up to 16 bits in parallel. SATA transmits one bit at a time in a serial stream. You do the math! I have used several Samsung NVMes for several years without a single failure. Good luck!
PCIe lanes explained - how many do you need on a motherboard?[^]

If you're going to tell someone to do that math; at least do it vaguely right.
A. m.2 is a maximum of 4 PCIe lanes wide.
B. That's only half the equation though; you also have to factor in the bit rate (PCIe3 is about 1.5x as fast/lane as SATA, PCIe4 about 3x as fast; but AFAIK still uncommon on laptops due to diminishing returns and power consumption).
Telling someone to do the math also ignores the fact that:
- The main advantage of SSDs vs spinning rust is in random IO where the former doesn't have to do a 10ms seek before starting to read; or that within SSDs.
- The main advantage of PCIe vs SATA is that the NVME interface was designed around how SSDs function not how HDDs do and is much more efficient as a result.
- Low end PCIe SSDs are nowhere near as fast.
VI. But I wouldn't have bothered posting B-5 if it wasn't for the  level mistake of A.

I have tested the relative speed for NVMes versus traditional SATA SSDs. NVMes are much much faster, especially when reading or writing large files. When dealing with a large number of smaller files, the difference becomes much less significant. By the way, I tested only Samsung products of both types.
That is what is important: The relative speed, not the number of PCIe lanes they occupy.

I have an HP Envy, but it's a printer!?!?
I’ve given up trying to be calm. However, I am open to feeling slightly less agitated.

Everyone buys HPs today. Dell tripped and Hp overtook them.
All computers are now made as cheap as possible in china.
Backup all drives SSDs or otherwise with an imager like Acronis or others to a usb drive religiously unless you fancy reinstalling you dev environment brick by brick more than once.

I splashed out and replaced my 9 year old huge tower PC with an HP EliteDesk 800 G5 Mini with i7 at the beginning of the year.
While, at times, the fan can be audible I am very happy with it, it's nice to have the space back too.

I don't know about successor. I've had an HP Envy m7 laptop for about 6 years. It had pretty good specs when I bought it for only $700 and I upgraded the OS and the HDD twice since then...once cloning to a 480GB SSD (huge improvement), then a clean install on a 1TB SSD. (another huge improvement)
After all these years, it's still a great laptop that is still snappy and actually compiles faster than my 3y/0 desktop system with better specs. I'd recommend it or a successor but would also advise for a clean install on the biggest SSD I could afford before actually loading it with dev components.

I'm surprised that Python doesn't have a format specifier for engineering notation. Oddly, the scientific notation is :e or :E depending on the lower/upper case desired for the exponent "E".
Does anyone actually use engineering notation anymore?

It is the same except that the exponents are limited to numbers that are divisible by 3, which makes sense for both engineers and scientists.

Yes, I think in Engineering notation. This comes from a lifetime of electronics engineering, where most calculations require one-and-a-bit significant digits precision and a huge exponential range. (In the good old days, a slide rule did the mantissa and you carried the exponent in your head.)
milli-ohms to megohms.
picofarads to farads.
... etc
A kilohm.nanofarad is a microsecond,for example.
So to me, 100,000 is really 0.1e6, not 1.0e5 (my mental mantissas range from 0.1 to 99).
In the dim distant past I wrote a couple of printf helpers to display numbers "my way".

Guido needs a good talking to when it comes to representing i as j.
What I mean: a complex number a + bi is written in Python as a + bj

This would be a lot more convincing if it was accompanied by a video of said duck.

A friend of mine just complained his coworker, a full-stack developer, writes crappy front-end and crappy back-end code.
He called him a non-stack developer.
Made me chuckle

I think "null-stack" would be more fitting, and it rhymes.
